Have you ever wondered why mostly women obsess over the likes of Justin Bieber? And why men don’t obsess over stars like Taylor swift? Watch to find out how the psychology of attractiveness functions differently between the sexes.

Disclaimer: This video only talks about two sexes, male and female. I also only talk about heterosexuals. This is because the research papers I have based this on only discusses these aspects. Taking such other factors into account would certainly be relevant, but the data just doesn’t exist (I couldn’t find anything at least).
